BEFORE USE
Mi Receiver and servo precautions
® Operate each servo to its full stroke and check if the pushrod binds or is loose. Unreasonable force applied to
the servo horns is bad for the servos and will also cause the battery to run down quickly. Be especially careful
when using 8.4V.
@ Make the stroke of each control mechanism somewhat larger than the full stroke (including the trim component) of
the servo horn. Adjust the servo horns so they move smoothly even when the trim levers and wheel or trigger
are Operated simultaneously in the same direction.
@ Be alert for noise.
Always solder noise killing capacitors to the running motor. Otherwise, the receiving range may be shortened or
there may be numerous dead points. If vibration causes metal parts to touch, noise will be produced and the
receiver and servos may operate incorrectly. We recommed the use of noiseless parts.
@Just because the receiver antenna may seem long, do not cut it off or fold it back on itself. The receiving range
will be shortened.
Noise killing capacitor (ceramic capacitor 0.01 4f)
Install at these two places,
at least.

@When using a commercial motor checker, always disconnect the motor from the speed control and radio. If it is
not disconnected, the amp may be destroyed.
@lf the FET fins (metal part) of the FET amp touch the chassis made of aluminum, carbon, or other conductive
material, the FET may be destroyed. When installing the FET amp, be sure that it does not touch such materials.
@A spare horn is provided. Use it as required.
@ Use double-side adhesive tape so that the receiver is not exposed to direct vibration. Also, install the receiver so
that it does not directly touch the frame or other parts and does not move.
@ When the receiver is installed on*a boat or is used where it may be splashed with mud and water, place it in a
plastic bag and wrap a rubber band around the open end of the bag. After use remove the receiver from the bag
to prevent condensation.
@ After mounting is complete, recheck each part, then check the transmitting range by making the transmitter a
antenna as short as possible and extending the receiver antenna fully and operating the set from a distance of
20m to 30m. The movement of each servo should follow the movement of the transmitter sticks. At this time,
place the vehicle on a stand, etc. so that it does not move.
@ The crystal can change from the outside of the receiver case. Always use a Futaba transmitter and receiver
crystal pair as the replacement crystals.
IMPORTANT : Receiver Antenna Routing
EXTEND WIRE AT LEAST 1" BEYOND TUBE
AND SECURE WITH KNOT
To obtain the best possible range (car to transmitter
distance) and reduce the possibility of interference, —— ANTENNA TUBE
please observe these antenna routing instructions.
Failure to follow these guidelines can result in loss ANTENNA SHORTENER
of control or limited range.
SERVO TAPE
1) NEVER cut your receiver's antenna wire.
Your system has been precisely tuned to the full
length of the stock antenna.

<
Excess antenna wire should NOT be tightly
coiled. To safely store the excess wire make
an antenna shortener from a small piece of stiff
cardboard. This will provide maximum reception
and prevent tangling and breakage of the wire.
3) When routing the antenna wire to the antenna
tube keep the wire away from battery and speed
control wiring. The high power of the NiCd
battery creates electrical "noise" which can cause
interference.
SNOW IS WATER
Remember that operating your FX10 on snow
or in wet areas is not recommended. Melted
snow becomes water which will damage or short
out your system's electronics.
